Hum,
Just a wild guess ,
but doesn`t the 1200 slot only support type I & II Cards?
Perhaps the EtherLink III is a type III?
If no, perhaps it could be a software issue in miami....(?)
Don`t think it`s power or a memory slot conflict with accelerator though...(if that helps)
And aside from checking that the pins aren`t bent there`s not much that can be fixed with the cards...
anyone else...
